When an Insulin Pump Malfunctions Leading to Underdosing, Select the Appropriate

When an insulin pump malfunctions leading to underdosing, select the appropriate reporting and sequencing of resulting conditions:

A) code first the appropriate diabetes code, then the mechanical complication due to the insulin pump, then the reason for the pump's presence, and any additional codes for conditions resulting from the underdosing
B) code first conditions resulting from the underdosing, then the mechanical complication due to the insulin pump, then the reason for the pump's presence, followed by the appropriate diabetes code
C) code first the reason for the pump's presence, then the mechanical complication due to the insulin pump, the appropriate diabetes code, and any additional codes for conditions resulting from the underdosing
D) code first the mechanical complication due to the insulin pump, then the underdosing of insulin, the appropriate diabetes code, and any additional codes for conditions resulting from the underdosing
